Flash Player 11.3 causes Firefox hang in my laptop as well. I've noticed that it consumes a lot of CPU and memory with even just opening one youtube video and sometimes even just opening the youtube site eats a lot of RAM which makes the browsing experience horrible.

We're working diligently in collaboration with Mozilla on fixing the remaining stability issues, but cannot comment publicly about a specific future release date. Please know that we're working hard to get a fix into the community. We also want to make sure that this fix does not introduce new problems. This means that we both need to identify and fix the problem, as well as conduct extensive certification testing. We're testing candidate builds now, but may need to iterate if we identify any newly-introduced issues during that testing. Once we have a fix available, we'll definitely be making announcements in the forums.

If you have a set of steps that always results in a crash, please share those with us now. We have a couple consistently reproducible cases which are fixed, but more examples of consistent crashes will be really helpful in terms of validating our fix, or identifying additional issues that need to be investigated.

Please know that our goal is to always release a high-quality product, and that we spend a great deal of time and energy ensuring that we test across as wide an array of hardware and software configurations as possible while continuing to bring Flash developers a modern generation of capabilities for creating beautiful, engaging and compelling experiences in your favorite browser. We apologize for any inconvenience, and are working hard to bring you a stable, secure and enjoyable experience.

While we conduct extensive testing on every new release (there were 2 private and 3 public beta releases for Flash Player 11.3 that spanned months, in addition to daily stability testing on our end that did not expose the issues that you are currently experiencing), there is a near-infinite number of combinations of operating systems, hardware and drivers in the field in addition to a steady pace of new technology. We do our best to ensure that our releases are stable, and constantly refine and invent new testing techniques to ensure that we release the highest-quality products possible.

If you need to revert to a previous version temporarily, that's okay. Please make sure that you always download Flash Player directly from Adobe to ensure that you're getting an authentic product.

We've released Flash Player 11.3.300.262, which addresses some general stability issues with Flash Player 11.3 on Firefox for Windows 7 and Windows Vista. If you're running Firefox 13.0, you'll also want to upgrade to Firefox 13.0.1.

If you're still seeing crashes after updating, please check out the following troubleshooting instructions, then start a new discussion so we can investigate your specific issue in further detail. (It quickly gets to difficult to glean useful information out of the 50-reply threads)

1.) Type "about:crashes" in your address bar, and copy the links for the time period where you encountered the crash.

Graphics hardware definitely sounds like a possibility. We'd like to know more about your configuration, so that we can at least blacklist that hardware to prevent other folks from running into the same problem.

If you could give us the output of dxdiag.exe on your computer, that would be very helpful.

Click Start > run > dxdiag.exe

In the forums, click Use Advanced Editor (it's a the upper right of the reply window), and attach the file.

I can only see how to attach videos and images, so I'll just insert it here. Good luck !:

It looks like your graphics drivers are a couple years old. I'd really like to know if you're seeing the same instability with the current Flash Player 11.4 Beta and the current display drivers for your system.
